CAR-COUPLING.

SPECIFICATION forming part of Letters Patent No. 380,585, dated April 3, 1888.

Application filed August 5, 1887. Serial No. 246,243.

To aZZ whom it may concernh Be it known that I, ANTOINE MiiLLER, of Terre Haute, in the county of Vigo and State of Indiana, have invented a new and useful Improvement in Oar-Couplings, of which the following is a specification.

My invention is an improvement in carcouplings, consisting in certain features of construction and novel combinations of parts, as will be hereinafter described and claimed.

In the drawings, Figurel is an end view of a car provided with my improvements. Fig. 2 is a side view of the improvements. Fig.3 is a longitudinal section through the drawhead. Fig. 4 is a detail view of the link-adjusting bar. Fig. 5 is a detail view illustrating the pin and the connecting-rod for joining it with the pin-elevating devices. Fig. 6 illustrates in detail the construction of the lifting arm and its operating-shaft, and Fig. 7 shows the inside of the top wall of the draw-head.

In carrying out my invention I provide on the end of the car bearings for the elevatingshaft A, which has suitable handles, a, by which it maybe turned. These bearings are by preference formed in a bracket, B, fixed to the car, as shown. I provide this shaft A with a radial pin, 0, which operates the lifting-arm D in the manner presently described. The lifting-arm D, which elevates the coupling-pin, is not secured rigidly to the shaft A, but has one end pivoted, and is provided with a portion arranged to be engaged by the pin 0 as the shaft Ais turned. By such construction the turning of the shaft may be caused to effect an upward movement of the outer end of the arm, and a consequent elevation of the coupling-pin.

It is preferred to employ the construction shown, in which the arm has lugs or cars d, which are journaled on the shaft A, forming a pivot for the arm. These lugs fit on opposite sides of the pin 0, which in practice engages that portion of the arm D at the base of the slot between the lugs d.

In the arm D, I form longitudinally a slot, D, the outer end of which is closed by a pinlike cross-bar, d. The connecting-rod E is also slotted longitudinally at e, the crossbar d, fitting in said slot, forming a connection between said bars D E, which permits a sliding (No model.)

of such parts one upon the other, as shown, and yet provides for the lifting of the connecting-rod. At its lower end the rod E connects with the coupling-pin F, being provided with a lateral stud, e, having a non-circular head, 6 which corresponds with a similarly-formed opening, f, in the coupling-pin. By this construction the coupling-pin and oonnectingrod may be set properly to permit the head 6 to move through opening f to effect the connection or detachment of the parts E F; but when such parts are in normal arrangement the head 6 will be so arranged with reference to opening f as to lock the parts in connection.

The draw'head G has openings g g for the pin F, and has its mortise G partially closed at its forward end by the flanges g, which project from the top and base walls of said mortise toward each other. The lower one of these flanges forms a pivot'bearing for the link H in the adjustments of such link, while the upper flange serves as a protection for the front end of the link-adjuster I when the latter is not in use. This link-adjuster has its rear end or shank, 1, fitted in a reduced portion or extension, 1, of the mortise G, and in the upper wall of said mortise I form a recess, 2, which is fitted to wholly receive the body of the adjuster, so that when not in use the lower side or surface of thelink-adjuster will coincide with the wall of the mortise and form no projection or obstruction in such mortise.

The rear end of the link-adjuster is fixed to the shaft J, which extends to both sides of the draw-head and has handles J extended in an opposite direction from the link-adjuster, so that their weight will have a tendency to hold the link-adjuster up in its recess.

At its forward end the link-adjuster is extended laterally in order to engage the opposite sides of a coupling-link. This forward end moves close to and partially past the coupling-hook, being provided centrally with a notch or opening, 3, to receive the said pin.

When the parts are in the dotted position shown in Fig. 2-, the arm will be stopped by the wall 4 of the bracket B, and the pin will rest up in position to permit a coupling-link to enter the draw-head, and the jar incident to the meeting of two draw-heads will cause the pin to fall and the parts to assume the fullline position shown in said Fig. 2. By means of the link-adjuster the link may be held at different angles to enter higher or lower drawheads.

Having thus described my invention, whatl claim as new is 1. The combination of the coupling-pin, the shaft A, the arm D, having a longitudinal slot, D, and cross-bar d, and the connecting-rod E, connected at one end with the coupling-pin, and having a longitudinal slot, 6, to receive the cross-bar d, substantially as set forth.

2'. The combination of the bracket B, having stop-wall 4, the shaft A, the arm D, operated by said shaft and arranged to engage wall 4, the coupling-pin, and the connection between the same and the arm D, substantially as set forth.

3. The combination of the drawliead, the

coupling-pin having a non-circular opening, the connecting-rod having a lateral stud provided with a non-circular head conformed to the opening in the coupling-pin, and the arm whereby to elevate said connection and pin, substantially as set forth.

4. The combination of the draw-head, the coupling-pin, the connecting-rod connected at one end with said pin and provided with a longitudinal slot, 0, the arm D, having a slot, D, and provided with a cross-bar to enter slot 6, and also provided with lugs d, journaled on the shaft A, the shaftA having a pin, 0, arranged between the lugs d of the arm D, and

the bearing-bracket B, having a stop-wall, 4, 5

substantially as set forth.
